• Q: How to install the rear shock absorber for the torsion beam type suspension on 2009 Toyota Matrix?

  A: The installation of the torsion beam type suspension rear shock absorber begins with the use of Special Service Tools 09727-30021 and 09727-00010 to compress the rear coil spring. Avoid using an impact wrench to prevent damaging the tools during this step. And the shock absorber assembly receives the coil spring while maintaining the spring end in the depression of the lower spring seat. The correct installment sequence includes placing the rear No. 1 spring bumper then following with the rear coil spring upper insulator and the rear suspension support assembly before proceeding to install the rear spring front bracket sub-assembly and rear suspension support and finally the rear No. 1 shock absorber cushion washer with proper orientation. Fasten the piston rod of the rear shock absorber with a 6 mm hexagon socket wrench prior to tightening the new nut to 39 Nm (398 kgf-cm, 29 ft-lbf). Connect the rear shock absorber with coil spring by attaching a bolt to the lower section and upper side nuts with a torque of 80 Nm (816 kgf-cm, 59 ft-lbf). The rear shock absorber combined with coil spring needs a nut attachment before positioning the rear wheel for final tightening up to 103 Nm (1050 kgf-cm, 76 ft-lbf). Both left and right sides require installation of their trim panels with light covers and garnish assemblies while securing all components with tight fasteners. Lower the vehicle until it reaches a stable suspension position while bouncing it multiple times. Following this position the rear axle beam with a wooden block underneath to load the suspension before accurately placing the rear shock absorber with coil spring according to specifications. Apply tightness of 80 Nm (816 kgf-cm, 59 ft-lbf) to the rear shock absorber with coil spring nut during standard vehicle height observations before evaluating rear wheel alignment and checking the front wheels' direction. Follow the process of disconnecting and reconnecting the negative battery terminal cable for longer than two seconds and perform necessary zero point calibrations on the yaw rate sensor as well as the steering angle sensor.
